Here's a link on Sony.com about their brand new smartphone the Xperia Z1s & its adventure to meet the manatees! I must say the image quality is quite good right out of the camera phone & I had it submerged for hours & hours with no problems (it was warm and slow for seeing manatees but the Xperia patiently waited, clipped to me while I snorkeled about).

I believe Eric wanted to do more of an article on this but possibly the timing was off. Sony did link to WetPixel though:
